I'd be interested in the calculations that used to come up with this estimate, I'd be surprised if the parasitic loses associated with the supercharger were more than 2-3 HP, if even that.
Did you mean that disconnecting the supercharger will result in a 30-50 HP overall drop in power output?
My daily driver is also a C230 Kompressor with 161K miles and my supercharger is also making noises, however it seems to be an intermittent problem. At cold startup when the ECU uses the supercharger to provide aux air to warm up the O2 sensor the noise is pretty loud. It does sound like a bunch of rocks rattling around in a coffee can!! But at higher RPM ranges I can't seem to hear it at all, very strange.
I've done some searching and it appears the Eaton M62 supercharger has a problem with the "snout" bearing that supports the input pulley, most of the time the failure of this bearing is the problem. The bearing is apparently replaceable and available, do a search for the details if you want to explore the option of fixing the supercharger.
